Nature 2 Spa Test Strips

Spa Test Strips for Monopersulfate, pH, and Alkalinity

These test strips test for alkalinity, PH and MPS ONLY!

You should always balance alkalinity first, then pH, as they are related yet separate aspects of the water quality. As you probably know, increasing alkalinity increases the pH, but not the other way around, which is why we test alkalinity first, and then do our adjustments.

Its not rocket science, but it does need to be fairly accurate to work correctly. So, its equally important to be sure your test kit or test strips are stored properly and not out of date. And remember, cold water testing results are not always accurate, so don't try to test new water too soon. Let it come to temperature, and then adjust, wait AT LEAST five minutes, and test again to be sure you got it right. Always adjust in small amounts, because its easier to add more than to take it away.
